Small colorectal polyps, often adenomatous, require removal. Hyperplastic polyps, common in the rectum, may indicate proximal adenomas, warranting treatment and total colonoscopy.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Pathology

Background:

  • Small colorectal polyps (<0.5 cm) are frequently encountered during colonoscopy.
  • Histological classification is crucial for determining the clinical significance and management of these polyps.

Purpose of the Study:

  • To review the histology of small colorectal polyps removed during total colonoscopy.
  • To determine the clinical significance of small adenomatous and hyperplastic polyps.
  • To assess associations between polyp types and locations.

Main Methods:

  • Retrospective review of histology from 766 small colorectal polyps (<0.5 cm).
  • Analysis of polyp types (adenomatous, hyperplastic, mixed) and locations (colon vs. rectum).
  • Correlation of small polyp histology with the presence of associated large adenomas.

Main Results:

  • 60% of polyps were adenomatous, 22% hyperplastic.
  • Hyperplastic polyps were more common in the rectum (71%), adenomas in the colon (63%).
  • Colon hyperplastic polyps were associated with adenomas in 75% of cases; rectal hyperplastic polyps with proximal adenomas in 63%.

Conclusions:

  • Small colonic polyps are typically adenomatous and should be removed.
  • Small rectal polyps are often hyperplastic but may signify proximal adenomas, necessitating treatment.
  • Biopsy of small polyps is important if no other neoplasm is found; hyperplastic polyps warrant treatment due to uncertain significance and association with adenomas.
